There is a guy on YouTube (“1500 Overland”) that has a set up you described. He has the ORP but he had to change out his rear springs to non-ORP after he installed the Fabtech coilovers just to reduce the rake. You can contact him through his YouTube channel.
I’ve seen pictures of an install exactly as you describe. The angles looked wrong to me. The 6” kit comes with longer steering knuckles and the Readylift UCA’s were engineered for stock knuckles. I did the BDS 6” and their UCA’s. I’d recommend matching the UCA’s with the kit.
I don’t like the MDS at all. When it kicks in, I feel it in my seat and in the gas pedal. The truck feels like it’s having trouble getting out of its own way. And with my tuned exhaust, it gurgles loudly. I disable it every time I drive.
In most winter conditions, you don’t want to use your lockers. Really only if you are already stuck or trying to avoid being stuck at relatively low speeds. This is especially true in mountain driving with tight turns and off camber surfaces. Lockers will put you in the ditch before you know it.
